The Sixth edition of this important work. Part 1, by May Abraham: a Practical Guide. Part 2, by Roland Burrows: Acts Relating to Factories and Workshops with Explanatory Notes. 627 pages including two Appendices and an Index. This edition is described as having been thoroughly revised and brought up to date. Condition: The green cloth covered boards are a little rubbed and worn, but the book is overall externally clean, with the gilt titles bright a previous owner has made a list, in pencil of the additions and dates of this work, on the verso of the front frame paper. There is a little age darkening to the pages, but overall this is a firm, clean copy.
